Abstract: A screw having stacked screw heads includes a screw shank portion with a thread and a screw head portion rigidly connected to each other. The screw head portion is driven to bring the screw shank portion to rotate. The screw head portion includes a first screw head and a second screw head. The first screw head has a first shaped groove on its top plane to receive an operating torque. A neck portion is connected to a bottom plane of the first screw head and a top plane of the second screw head. The second screw head has a second shaped groove on its top plane. The neck portion or the connection between the neck portion and the first screw head or the second screw head has lower torsional endurance than each of the first screw head and the second screw head.

Abstract: A multi-input multi-output antenna system capable of being disposed in an electronic device and the electronic device including the antenna system have a low-frequency antenna assembly and a high-frequency antenna assembly. The low-frequency antenna assembly includes multiple low-frequency antennas that are spaced apart from each other by a distance. The high-frequency antenna assembly includes multiple high-frequency antennas that are spaced apart from each other by a distance. One of the high-frequency antennas is structured as a low-profile dish antenna and is located between the low-frequency antennas, so that the antenna system has smaller volume and height, and better isolation and radiation patterns.

Abstract: A channel loading pre-adjusting system for 5G wireless communication adapted to be used for communicating at least one user's device with a core network includes a radio unit, a distributed unit in communication with the radio unit via a specified transmission channel, and a central unit. The distributed unit periodically detects transmission conditions of the specified channel and determines whether to issue an alarm signal accordingly, and in response to the alarm signal, the central unit determines whether to suspend data transmission via the specified transmission channel. The transmission conditions include a first group of latency parameters realized in a first number of consecutive detecting operations of the distributed unit and a temporal threshold derived from a second group of latency parameters realized in a second number of consecutive detecting operations of the distributed unit, and the first group of latency parameters are dynamically updated with time.
